文中分别对传统的有源电力滤波器（ActivePowerFilter，APF）和PWM（Pulse—widthModulation）整流器结构和原理进行研究，分析了它们基本功能、主电路拓扑结构、控制特性及策略的异同。根据二者的相似性对PWM整流器的拓扑结构加以转换和改进，使其衍生出具有有源电力滤波器的功能和特性。该有源电力滤波器不需要对负载的电流进行采样，而是将电流采样点前移到网侧，并通过相应的空间矢量算法以保证网侧具有较理想的电流。所得结论经过Matlab／Sirnulink仿真后，证实该有源电力滤波器结构的有效性。

The structures, principles of traditional active power filter （APF） and PWM rectifier were researched respectively. The similarities and differences between their basic functions, topologies and control strategies were analyzed. According to their similarities, some changes and improvement in topologies of PWM rectifier were made to acquire the functions and features of an active power filter. This active power filter didn＇t need to sample the load current, but moved the current sampling point to the network side and took the corresponding space vector algorithm to ensure the network side with ideal current. Through establishing the model in Madab/Simulink, simulation results compared with the original APF have shown that the new structure of APF is effective.
